For isobaric gas compression to a volume of 150 dm3, work of 100 J. Find the initial gas volume if its pressure is 100 kPa.
Initial data: Vк (gas volume after isobaric compression) = 150 dm3 (0.15 m3); A (work performed when compressing gas) = 100 J; P (gas pressure) = 100 kPa (100 * 10 ^ 3 Pa).
The initial gas volume is determined by the formula: A = P * ΔV = P * (Vn – Vk), whence Vn = Vk + A / P.
Calculation: Vн = 0.15 + 100 / (100 * 10 ^ 3) = 0.151 m3.
Answer: Before isobaric compression, the gas volume was 0.151 m3.
